Holanda or olandilla

The fabric known in Spain as Holanda or olandilla is a very fine linen fabric used to make shirts. It had to be soft and cool to the touch.
See the Diccionario de Autoridades – vol. IV (1734)

Curiously, and thanks to the book commemorating the masquerade held in Malaga, we can intuit that it was also the fabric used to recreate or simulate the nudity of the pagan gods.
